To. all whom it may concern: I Be it known that we, JOHN A. KNISELY andJOHN HORSFIELD, citizens of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented certain new anduseful Improvements in Windows, of which the following isaspecification. Our invention relates particularly to the constructionof the sash-frames and the pul ley-stiles or jambs and or" the means forsuspending, pivoting, and locking the sashframes; and it consists ofimprovements in certain features of the invention described in theapplication for Letters Patent, Serial No. 718,660, filed on May 29,1899, by the said John Horsfield.

The improvements involved in this invention consist of a combinedsliding and pivot ally-swinging window sash, yielding pulleystileshaving ways formed therein for the side rails of the sash, and ways forthe sash chains or cords; in a slidable pivot-pin device, which alsoserves as a sash-lock; in combining with a slidable pivot-pin a sashcord or chain; in

securing the sash chain or cord to the pivotpin so that it may notbecome accidentally detached, no matter in what position the sash may beplaced; in housing the sash-chain in the pulley-stile so that it may notinterfere with the swinging of the sash on its pivots, and in variousother combinations and details of construction hereinafter described,and pointed out in the claims.

In the drawings forming a part of this application, Figure 1 is a frontelevation of a window built in accordance with our invention, the uppersash being shown swung upon its pivots in an open position and a partofthe frame being broken away to show the manner of yieldingly supportingthe pulleystile. Fig. 2 is a cross-section on line 00 a; of Fig. 1.Fig.8 is a detail, on a larger scale than Figs. 1 and 2, showing asection of the window frame, sash, and the pulley-stile, and

showing the application of the pivot-pin de- Fig. 4 is a cross- Fig. 5is a vice and the sash-chain. section on the line y y of Fig. 3.

detail, partly in section, of the device for attaching the sash-chain tothe window-sash, the same forming a part of the pivot-pin device.

Beferring to the drawings, A represents a Fig. 5.

window frame or casing of the usual box-like form, iii which are locatedthe sash-weight 1 chambers a and partitions a the latter having openingsa therein through which the sash-chain e and sash-weights or may bereached for the purpose of repairs or alterations. The partitions aextend from the top to the bottom of the frame, and have secured theretocurved springs c, which are formed from flat metal, and are sopositioned that tion of said springs being to yieldingly hold the stilesagainst the edges of the side rails of the window-sash.

The jambs or pulley-stiles C are formed with plane sides and back,asclearly shown in Fig. 2, but with their outer face having formedtherein beveled longitudinal grooves c and in the bottom of said grooveschannels 0 the latter forming'slideways for the pivot-pins and housingsfor the sash-chains and the beveled portions of the grooves c formingbearings for the correspondingly-beveled edges of the side rails D ofthe windowsash B and B, the former representing the upper sash and thelatter the lower one. In the stiles, at points opposite the center ofeach sash, holes 0 are bored to receive the pivot pin when the latter isthrown out, as will be explained. It will be understood that other holesmaybe bored in the stiles at other points for the purpose of locking thesash in open positions.

Let into each side rail D of the sash B and B is a pivot-pin, sash-lock,and sash-chain holding device, which is formed as follows: A flat metalplate E is provided with suitable holes for the passage of screws, bymeans of which screws the plate is secured to the edge of the side railD and is centrally perforated for the passage of a tubular casing orsleeve 6, the ends of which are flanged, as shown in The flange on theouter end of said sleeve serves to prevent the slipping off of thestirrup e, which is secured to the end of the sash-chain e while theflange on the inner end of said sleeve prevents the latter from beingthrownor pulled out of the plate E by is tilted or turned upon itspivots thebeveled edges of the side rails will bear against and pushback the stile and the sleeve will slide outwardly as the pulley-stilerecedes from the sash. Slidably secured in the sleeve 6 is a bolt.d,.nearthe innerend of which and.

at right angles thereto is secured afpin d the head of which projectsbeyon'd'the face of the side rail and serves as a means for shootingthebolt. Secured to the face of the side-rail-is a recessed or dished plated which is suitably slotted to'receive the pin d 'and prevent thesliding movement. Preferably the plate d willbe let into the face of theside rail, so that neither it nor the head of the pin will projectbeyond such face. When I it is desired to lock the sash in position, the

pressure of the beveled portions ofthe stiles" against the side rails ofthe sash will be sufbolt: is shot into-the hole 0 but normally saidboltis in the position shown in Fig. 4, whereby itforms, with the sleeve 6,a pivotpin for the sash and a strong means for holding the end of thesash-chain, the strain be- 1 ing onQ-both bolt and sleeve.

When the sash is tilted, the tension of the springs c' against thestiles and the resulting ficient to hold the latter in any desired posit-ion.

. Having thus described our invention, what we claim as new, and desireto secure by Let-7 ters Patent, is-- 1. Incornbination with awindow-sash, and

fram e, sash chains or cords, pulley-stiles yieldingly supported in saidframe and having formedv therein channels for the sash-chains,

pivot-pins secured to the chains, said pins beingformed of asleeve'slidably secured in the sash, and a bolt sliding in said sleeve.

In combination with a-window-sash, a

secured i-nsaid plate and in a suitable recess Normally the sleeve willbe in the position shown in Fig. 4; but if tl1e sash in the sash, a boltsliding in saidfsleeve and recess, and means for shooting said bolt.

3. In combination with a window-frame, and sash, a sash-chain, asash-pivoting and chain-holdin g device composed of a perforated platesecured to said sash, a sleeve Slidably in said sash, means for securingthe chain to recess and means for shooting the bolt.

4. In combination with a window-frame, and sash, a sash-chain, asash-pivoting and chain-holding device 1 composed of a perfo- 'ratedplate secured to said sash, a sleeve slid ably secured in said plate andin a suitable recess in the sash, means for preventing the sleevefrombeing with drawn'from said plate, a stirrup for securing the chainto theIsleeve, means for preventing the accidental'removal of thestirrup from the sleeve, a. bolt'sliding in said sleeve and recess, andmeans for shooting said bolt.

5. In combination with a yieldingly-supported pulley-stile having achannel formed therein, a sash-pivoting device composed of a perforatedplate secured to said sash, a

sleeve slidably secured in said plate and in a suitable recess in thesash and adapted to slide in said channel, a bolt sliding in said sleeveand recess, and means for shooting said bolt. v

6. In combination with awindow-fra1ne, a sash having beveled side rails,yieldingly-supported pulley-stiles having correspondinglybeveled groovesand having channels formed in the bottom of said grooves, asash-pivoting devicecomposed of a perforated platesecured to said sash,a sleeve slidably secured in said plate and in a suitable recess in thesash and adapted to slide in said channel, and a bolt adapted to slidein said sleeve and recess, and means for shooting said'bolt.

In testimony whereof we'aiiix our signatures in the presence of twoWitnesses.
